Windows 10: Dropped frames in Firefox after upgrading from Win7 to Win10

I've upgraded from Windows 7 Ultimate 64 bit (installed on my SSD) to Windows 10 Pro 64 bit.
Since then, I've dropped frames on YouTube using Firefox at [email protected] (VP9 308) and at [email protected]/25/30 (VP9 313).
I used to play them smoothly without any frame lose on Firefox in Windows 7.
I've 1080p monitor, but I prefer to play higher res, because of the video quality is much better (higher bitrate).
Tried enabling/disabling WebRender, WebGL, Hardware Acceleration. Tried Firefox Portable, older version an reinstalling Firefox. Nothing Works...
I've the latest Nvidia drivers, and the latest Firefox version.

Sample videos:

2K @ 60 (4K @ 60 is too much for my machine...)

https://www.youtube.com/watch?v=YsUB6Jia4v4
4K @ 24

I can play them in VLC (in the same res) without frame lost in Windows 10, but not on Firefox...
I have another HDD with Windows 7 Ultimate 64 bit and latest Nvidia drivers and Firefox release, and these videos play smoothly in Firefox without a single frame lost.

My Specs:
i5-750 @ 2.67 (stock)
8GB RAM DDR3 1333Mhz Dual-Channel
MSI GTX 750 Ti 2GB GDDR5
GA-P55-USB3 MotherBoard
Kingston A400 SSD 240GB

Thanks

:)

jerky stop motion video, dropping frames after upgrading from win7


I just upgraded today.
We use the PC as a media center, so we watch live TV using ATSC cards.
Every TV program I tried, the video drops frames, watching someone walk across the screen, they do not move smoothly. The sound is ok. Seems every half second, frames drop.

This did not happen in win7.
I have 8gb ram, AMD phenom 9650 quad core, sata 2 drive, GTX260 nvidia card.
I upgrade the nvidia driver.

Would a newer video card make it work properly?

 

Win7 to Win10 upgrade issue ... 0xC1900101-0x30017 and then 0x40017

hi, Andre,

yes, i think my note did say that i already created the bootable ISO on a DVD and started the Win10 upgrade from there. i already contacted the vendor and he gave me a list of Win10 drivers, suggested the bootable ISO upgrade method but did not recommend
a new BIOS update.

My PC is a ZOTAC CI320none with an Intel processor running a licensed Win7 Home Premium SP1.
